Evidence for the semileptonic baryonic decay ( , ), based on a data sample of 772 million pairs collected at the resonance with the Belle detector at the KEKB asymmetric-energy electron-positron collider is collected. A neural-network based hadronic -meson tagging method is used in this study. The branching fraction of is measured to be with a significance of , where lepton universality is assumed. We also estimate the corresponding upper limit: at the 90% confidence level. This measurement helps constrain the baryonic transition form factor in decays.
